Over the next several years, Lafayette is expected to see new housing—much of it located along the Mt. Diablo Boulevard Corridor—so it is important to thoughtfully plan today how people will move through downtown tomorrow.

That's why the City has begun work on a new plan to guide how people move through downtown Lafayette—whether walking, biking, taking transit, or driving. The plan area extends from Acalanes Road to Pleasant Hill Road and includes the Lafayette BART station and the City’s commercial core—the heart of shopping, dining, recreation, and community events.
 
The Mt. Diablo Boulevard Corridor Multimodal Mobility Plan (“M3”) will create a shared vision for how people in our downtown move around the vibrant mixed-use corridor over the next 20 years. M3 is about making it easier and more appealing to get around downtown—whether you’re heading to school, meeting friends, shopping, or catching BART. The goal is to identify where and how improvements to the transportation network can:

  • Make everyday trips easier without a car, including safer and more convenient options for walking, biking, and accessing transit
  • Enhance the downtown experience, support local businesses and create a more welcoming, community-oriented environment
  • Reduce reliance on private vehicles over time, particularly as Lafayette continues to grow.

As of Spring 2026, we are currently selecting and onboarding a consultant team to help us with this important work.
